"Ugh..., it hurts," Jess moaned, she grabbing as her hairy midsection and doubling over, gaining a much different posture, something closer to what most animals need to see when standing on all fours.
Mary took a step or two backing away from Jess, she wanted to see what would happen, but afraid of Jess retaliating her dislike of becoming likened to a goat, and changing more with the addition of a second vial so soon after taking the goaty one. Not too sure of what all the magical vials had as properties, Mary thought this as fun, but even fun-times have rules.
Jess looked to be gaining in size, as if her girlish petiteness was becoming something with greater bodily strength, bulking her muscles about her shoulders, upper arms, and her thighs.
An already partial changing of her face to become that of a goat took on new contorting changes, as from these happening, Jess let out a wailing scream.
"You are trying to kill me..., I shall kill you when this is through, kill you for all these pains, owe..., owe...woo!" Jess strained to get her words out a changing mouth, her human teeth she spitting out as new ones pushed out the previously human teeth, making for a mouth better suited for grazing.
Mary stood and stared at her friend, seeing mostly how the eyes of Jess were changing. Watching as human oval shaped eyes became much larger, being round, and then the teal green of eye iris shaded into a glistening golden color. Cringing at the sight, wondering if it actually hurt Jess, but seeing was believing as the eye pupils of Jess kinked, becoming then as sharp cornered rectangles.
Jess began to huff her breathing, taking ever deeper inhaled breaths and exhaling them in a huffing manner, another sign of her changing and growing.
Slowly, a bit of movement at a time, as Jess feeling her new bodily strength began to resurrect her posture to that of standing uprightly, as on then cloven hooves, very goat like legs, her thighs much broader, making her groin deeper, and when fully righted, Jess looked at Mary with a sneering grin.
Muscular in the extreme, Jess stood before and slightly then taller than Mary, her muscular chest had lost all signs of those perky human breasts. Mary stood and gawking at what became of Jess, likely felt a sense of apprehension over what she helped to do to her friend. A friend who just moments before had threated to kill Mary for her making this all happen to Jess.
"Are, are you alright, is the changing of feelings finished, do you understand me, Jess, Jess, Jess?" Mary said, she from what stood there before her was originally Jess, but right then after all the changing stood a tall, lean of the middle but looking quite stronger at the chest, shoulders, and with a massively thicker neck.
Jess said nothing, she stood there looking down at Mary, glaring with a cold stare at what she once thought was a good friend.
Opening of her mouth, Jess having then the muzzle of a goat, teeth, and tongue, as the tongue lolled out the corner of her mouth, seemingly as something uncoordinated then for speaking anything humanly intelligible.
The harsh breathing began again, as if Jess felt an aroused sense of disdain for Mary. Not noticed soon enough by Mary, but the then forearms of Jess began to rise up, reaching out, they slid under th arms of Mary. A sudden jerking of those very strong furry arms and partially cloven hoofed hands, took a firm hold of Mary and drew her into a close hugging.
Mary squealed a frightened scream, terrified that her animalistic and much stronger friend, was then planning to do her some justifiable bodily harm.
"Please don't hurt me, Jess we are friends, this can get changed back, you can be human again, trust me!" Mary heard her say it, asking of Jess to trust her friend, something already to cynically foolish a hope. Nervous as what before this Mary thought of as making such changes happen was quite a humorous thing, she having the vials, planned many uses of them, doing as she thought it neat.
Jess continued to huff her breathing, the smell of her breath was near enough to make Mary faint.
Hoisted up off the floor, held in strong arms suspended helplessly in front of this very goat like Jess; Mary turned pale in the face, awaiting what might happen next.
Eyes met in each a stern stare at the other, Mary breathing was rapid, she silent, hung and waiting, felt then something prodding, poking at her panties.
"Huh, what is that, what the...!" Mary said and would have said more but from down where she could not see came a sensation so similar to a finger trying to impale itself up her vagina, she shuddered at the feeling.
A slight tearing sound came next, and from that same perky and excited vaginal opening Mary felt something hot protrude inside of her body.
"Oh, oh no, no, Jess, what is that...!" Mary asked of Jess, her word of "That" said in a sudden screaming from the penetration.
Deeper went the hot rod, inching along the tight vaginal walls of a then very excited, aroused vagina. Mary had felt this before, not from a man doing her, but by her own pleasuring of hr passions on some warm summer's nights.
Moaning with a seductive and delighted tone, Mary...
